Comparison of the effects of a multi-component vaccine and a formalin-killed cell vaccine on protection against enzootic of hemorrhagic pneumonia due to Pseudomonas aeruginosa in mink.
Effectiveness of a multi-component vaccine consisting of the common antigen (OEP) derived from Pseudomonas aeruginosa strain N 10 (serotype E) and toxoids of protease and elastase was compared with that of formalin-killed cells of strain N 10 on protection against enzootic of hemorrhagic pneumonia due to P. aeruginosa in mink. One administration of the multi-component vaccine (100 microgram each of OEP, protease toxoid and elastase toxoid) clearly prevented enzootic of hemorrhagic pneumonia due to P. aeruginosa (serotype G) in mink, while a vaccination of formalin-killed cells was much less effective in preventing an epidemic. The difference in mortality rates between two vaccines was remarkable.
